   An update that solves 13 vulnerabilities and has three
   fixes is now available.

Description:


   This update for xen fixes several issues.

   These security issues were fixed:

   - CVE-2017-5973: A infinite loop while doing control transfer in
     xhci_kick_epctx allowed privileged user inside the guest to crash the
     host process resulting in DoS (bsc#1025188).
   - CVE-2016-10155: The virtual hardware watchdog 'wdt_i6300esb' was
     vulnerable to a memory leakage issue allowing a privileged user to cause
     a DoS and/or potentially crash the Qemu process on the host
     (bsc#1024183).
   - CVE-2017-2620: In CIRRUS_BLTMODE_MEMSYSSRC mode the bitblit copy routine
     cirrus_bitblt_cputovideo failed to check the memory region, allowing for
     an out-of-bounds write that allows for privilege escalation (bsc#1024834)
   - CVE-2017-5856: The MegaRAID SAS 8708EM2 Host Bus Adapter emulation
     support was vulnerable to a memory leakage issue allowing a privileged
     user to leak host memory resulting in DoS (bsc#1024186).
   - CVE-2017-5898: The CCID Card device emulator support was vulnerable to
     an integer overflow flaw allowing a privileged user to crash the Qemu
     process on the host resulting in DoS (bsc#1024307).
   - CVE-2017-2615: An error in the bitblt copy operation could have allowed
     a malicious guest administrator to cause an out of bounds memory access,
     possibly leading to information disclosure or privilege escalation
     (bsc#1023004)
   - A malicious guest could have, by frequently rebooting over extended
     periods of time, run the host system out of memory, resulting in a
     Denial of Service (DoS) (bsc#1022871)
   - CVE-2017-5579: The 16550A UART serial device emulation support was
     vulnerable to a memory leakage issue allowing a privileged user to cause
     a DoS and/or potentially crash the Qemu process on the host
     (bsc#1022627).
   - CVE-2016-9907: The USB redirector usb-guest support was vulnerable to a
     memory leakage flaw when destroying the USB redirector in
     'usbredir_handle_destroy'.  A guest user/process could have used this
     issue to leak host memory, resulting in DoS for a host (bsc#1014490)
   - CVE-2016-9911: The USB EHCI Emulation support was vulnerable to a memory
     leakage issue while processing packet data in 'ehci_init_transfer'. A
     guest user/process could have used this issue to leak host memory,
     resulting in DoS for the host (bsc#1014507)
   - CVE-2016-9921: The Cirrus CLGD 54xx VGA Emulator support was vulnerable
     to a divide by zero issue while copying VGA data. A privileged user
     inside guest could have used this flaw to crash the process instance on
     the host, resulting in DoS (bsc#1015169)
   - CVE-2016-9922: The Cirrus CLGD 54xx VGA Emulator support was vulnerable
     to a divide by zero issue while copying VGA data. A privileged user
     inside guest could have used this flaw to crash the process instance on
     the host, resulting in DoS (bsc#1015169)
   - CVE-2016-9101: A memory leak in hw/net/eepro100.c allowed local guest OS
     administrators to cause a denial of service (memory consumption and QEMU
     process crash) by repeatedly unplugging an i8255x (PRO100) NIC device
     (bsc#1013668).
   - CVE-2016-9776: The ColdFire Fast Ethernet Controller emulator support
     was vulnerable to an infinite loop issue while receiving packets in
     'mcf_fec_receive'. A privileged user/process inside guest could have
     used this issue to crash the Qemu process on the host leading to DoS
     (bsc#1013657)

   These non-security issues were fixed:

   - bsc#1000195: Prevent panic on CPU0 while booting on SLES 11 SP3
   - bsc#1002496: Added support for reloading clvm in block-dmmd block-dmmd
